This quest is a bit tricky to start, and finding all the stone tablets to complete the quest can be a bit hectic. Sadly, this is the only way to get the Amenoma Kageuchi diagram in the game. The guide below is here to help you get the quest started and to provide the location of all four stone tablets.
How to Start The Farmer's Treasure
Starting the Farmer's Treasure quest isn't that simple as there are two pre-requisite quests you will need to complete first:
- Chisato's Letter
- Part of The Sakura Cleansing Ritual
Once you have the Memento Lens and have completed the letter delivery quest, head to Jinren Island.
There you will find a man named ???, look in a nearby tree for the key to open his cage after defeating the nearby enemies. He will reveal himself to be Saimon Jirou and send you on a quest to find four old stone slates scattered around Narukami Island.

Where to Get the Old Stone Slates in The Farmer's Treasure
The tablet locations are a bit spread out, so use the pictures below to help you find all four pieces. Keep in mind that the Stone Slates will be represented by small sparkles like the food you usually find in-game:
Old Stone Slate #1: Inside Konda Well in a wooden box.
Old Stone Slate #2: In the Araumi Ruins, near the broken steps in a pile of dirt.
Old Stone Slate #3: In the Araumi Ruins, near the entrance to the Perpetual Mechanical Array in a broken vase.
Old Stone Slate #4: Located in a tent on the beach below the Kamisato Estate.
- After you nab all four, teleport back to Jinren island and talk to Saimon Jirou; here will tell you the location of a fifth tablet.
- Go to the tablet locations and dig up several spots until the Traveler and Paimon realize the information was fake.
- Go back to Jirou's location to find him gone and then swim to the island where he was first located.
- Here you will fight several waves of enemies to free Jirou; make sure to use buffs and watch your health.
- After freeing Jirou, unlock the nearby gate and place the slates in the holes; you will now need to light up every slate in the room.
- Finally, you just need to open the treasure chest and then head back to Konda Village after a brief conversation with Jirou.
After talking with Jirou and his parents, you will receive your quest rewards, including the diagram for the Amenoma Kageuchi.
